But it's a good story, Joule decided that there must be a direct relationship between work and heat.
所以说,这只是一个不错的故事而已,焦耳认为功和热之间,一定具有某种直接的联系。
It must not be easy to write your own work.
你自己创作一定很难。
So, the total work that we can get out must be zero, out of the whole sum of them.
因此,我们可以从这两个热机,得到的总功,一定是零。
Now, I don't know how far back it goes but it must be that in ancient times some people would say, all right you're going to be doing more work or you're contributing more to this enterprise, we'll give you a bigger share of the profits.
我不知道这能追溯到什么时候,但在古时候肯定有人说,好吧,你比别人干得多,你对公司的贡献更大,我们会把收入的大头给你
So this must be equal to work, right?
那么这个必须与功相等?
It makes sense, right, because you know we got less work out and delta u is the same right, so it must be that less heat got transferred.
这是显而易见的,因为输出的功更少,且Δu相等,所以需要的热量更少。
